Gasoline and diesel prices are reduced for the first time this year beginning Sunday, as oil and gas prices in international market continue to fall.

The wholesale price of regular gasoline and diesel prices declines by 300 yuan ($47) per ton, according to the National Development and Reform Commission, China's top economic planner.

Under an oil pricing mechanism started in 2009, the government considers adjusting domestic refined oil prices when international oil prices change more than 4 percent within 22 working days.

Since then, China has adjusted fuel prices 16 times, with 10 price hikes and six reductions.

由于国际市场油气价格持续下跌，从周日开始，国内汽柴油价格年内首次下调。根据中国最高经济规划机构——国家发改委的决定，汽柴油的批发价格均下调300元每吨。2009年开始实施的油价机制规定，当国际油价连续22个工作日变化超过4%时，政府才会考虑调整国内成品油价格。自此，我国共调整油价16次，其中10次上调，6次下调。

【讲解】文中的domestic refined oil price即指国内成品油价格，refined oil是指成品油，refine是指精炼，提炼。gasoline是指汽油，diesel是指柴油，原油我们可以说成crude oil。the National Development and Reform Commission是指国家发改委。
